This can happen if the filament for any reason does not reach the nozzle. - most likely, the filament roll does not roll freely and is blocked somehow, maybe miss tangled - you habe a Partial clogged hotend - you running to you printer to fast, an the flow can’t keep up - extruder motor runs to hot or has a malfunction in cable or connector
